CHP (powder form) is a readily dispersible polymer additive designed to provide cuttings encapsulation and shale stabilization in freshwater to saltwater drilling fluids ranging from low solids to weighted muds. CHP acts as a viscosifier, friction reducer, and flocculants, while also providing some fluid-loss control. CHP also delivers cuttings encapsulation and improves wellbore stability, making it ideal for slim hole and continuous-coring applications.

Application/Function

Readily dispersible and does not form “fish eyes”

Excellent cuttings encapsulation limits cuttings dispersion

Improves shale stabilization

Helps prevent balling on the bit, stabilizers and bottom hole assembly by coating and lubricating solids

Enhances removal of drill solids

Can be used to viscosify clear-water and low-solids drilling fluids

Advantages

Recommended Treatment

Add CHP in concentration of 0.7 to 4.3 kg/m³ (0.2 to1.5 lb/bbl) to any active system. Mix slowly through a jet mixer or sift slowly into the vortex of a high-speed stirrer.
